Not for the Scales but interesting block libraries.
I found the ones Esquivel linked were more than sufficient
Actually as far as our Standards are concerned I've bypassed use of AEC content.
File Auditing crashes and failures have been out of hand with AEC content throughout the 2007 file format.
Compatibility issues, cross platform issues, etc...
Not to mention file sizes increase more than the value it has posed to our uses.
It is a preference I haven't taken lightly but chose the simplest solution in not using them.
